2 Claims.

This invention relates to improvements in lamp bases, being particularlydirected to one incorporating a revolving element.

In general, it is an object of this invention to 5 provide a novel lampbase incorporating a revoluble globe, the assembly and construction ofthe base being such as to provide a relatively simple and eflicientsupport to permit axial displacement of the globe while at the same timeproviding for 10 a simple and efficient assembly of the electricalwiring therefor.

These and other advantages, capabilities and features of the inventionwill appear from the subjoined detailed description of one specific eml5bodiment thereof illustrated in the accompanying drawing, in whichFigure 1 is a front elevation of a lamp incorporating my invention.

Figure 2 is a front elevation in section of the 20 lamp base.

Referring to the reference characters in the drawing, numeral lrepresents a base plate having a hollowed interior and having formedintegral therewith at diametrically opposite sides,

25 hollow ball formations II and H.

Upstanding perpendicularly from the base plate and integral therewith,and the ball formations thereon, there is provided a frame or support inthe nature of a ring l2, such ring serving in this 30 instance is ameridian circle for the globe 13 carried thereby. As shown in Figure 2of the drawing, the ring |2 adjacent one of the balls I I has a bossformation Hi, the interior of which is hollowed and threaded as at I5,and which has 35 a restricted aperture l6 leading into said ballformation II.

On the frame or ring I2, and diametrically opposite to said first namedboss I is a second interiorly hollowed boss ll, of interior diameter 40slightly greater than that of the first named boss.

On the frame or ring l2 and extending upwardly of the center axisthereof, there is provided the usual type of light socket l8, upon whichis carried the light bulb (not shown) and the lamp 45 shade I9 indicatedin Figure 1.

As shown in Figure 2, the globe l3, which is hollow, has diametricallyopposite axial apertures 20 and 20', in which are disposed respectivelybushings 2| and 2|, each of which has restricted 50 neck portions 22,forming a tight fit with the apertures of the globe for maintenancetherein. Each bushing has a central aperture 23 of size sufiicient toaccommodate sleeve 24 passing therethrough and through the globe, saidsleeve having one end of reduced diameter and threaded as at 25, tocooperate with threading l of boss The annular surfaces 28 of thebushings 2| and 5 2| act against annular surfaces 21 of the bosses onthe inner periphery of the frame, such elements serving as bearings forthe rotating globe.

In assembly, the bushings 2| and 2| are placed in the hollow globe atthe axial apertures 20 and thereof, and the globe aligned with suchaxial apertures opposite the inner peripheral apertures of the bosses l4and IT in the frame or ring |2. The sleeve 24 is then passed through,the boss through the globe l3 and the bushings 2| and 1 2| mountedthereon, and then rotated, causing the restricted threaded end 25 of thesleeve 24 to be firmly disposed upon meshing with the threads l5 of theboss l4 in the relatively restricted aperture of such boss. 20

Thereafter, wires or leads 28 are passed either downwardly or upwardlythrough sleeve 24 for making necessary wiring connections, the lowerportion of the wire being passed through aperture 29 of the base plateadjacent boss I4. 25

It is obvious that various changes and modifications may be made to thedetails of construction without departing from the general spirit of theinvention as set forth in the appended claims. 30

I claim:

1. A device of the character described, comprising a base, a ring-likeframe upstanding therefrom, bosses formed on diametrically oppositeportions of said frame, a sleeve disposed within said bosses, a globehaving axial apertures mounted for rotation on said sleeve, a lampsocket mounted on said frame and wire leads passing from said socketthrough one boss, through said sleeve and thence through the other boss.

2. A device of the nature described, comprising a base, a ring-likeframe upstanding therefrom, bosses formed on diametrically oppositeportions of said frame, one of said bosses being interiorly threaded, asleeve disposed within said bosses, said sleeve being exteriorlythreaded at one end for cooperation with the interiorly threaded boss,

a globe mounted for rotation on said sleeve, a lamp socket mounted onsaid frame, and wire leads passing from said socket through one bossinto said sleeve and out through the other boss.
